Hello everybody.

I have a question about generation of return current in plasma beam interaction process:

we enter an electron beam in a plasma medium, and this electron beam generate a return current in plasma, I want to know how electron current can produce a return current in plasma?
thanks

If you shoot enough electrons, the source gets positively charged and your target gets a negative charge. A potential difference in a conducting medium leads to a current flow.
I don't think this is particle physics.

But it is plasma physics.
